MOUNTING THE SENSOR
Sensor location.
For proper operation, the sensor should be installed close to the bulb or the
bow of the ship, avoiding areas where it may be damaged by the anchor chain.
It is, of course, necessary to select a part of the hull that is submerged under all
load and speed conditions.
For 2 axis speed logs the transducer should be positioned as deep as possible
on the hull. The transmitting surface of the transducer must be installed
horizontally.
A typical recommended area for installation is fore part of the bow thruster
room.
The sea valve with sensor can be installed in a balast tank, but it is not
recommended. It is necessary to position the sensor on a hull section which will
ensure a laminar water ow for all angles of measurement. If such a at section
is not available, the shipyard must construct a suitable bed. If the vessel is
designed with a box keel, this can be used for installation of the sensor. In this
case, special length hull tting and sensor may be ordered from SKIPPER.
Before hull tting installation procedure is initiated, always check that the hull
tting valve can be properly operated and that the sensor can be removed in
the selected location. See installation manual for the valve solution for more
information.
